Feature Idea for the Healer Troop!

This is my idea, Healers can target any troop from the start of the match using a “Target Mode”. This would enable the Healer to target any type of troop, but not a specific troop. This could be done once per battle. It may need a nerf when the “Target Mode” is enabled, maybe around 5-10% to healer effectiveness because it could be overpowered in some cases I assume.Exclusions would be Heroes; because that could go a bit crazy. (I am aware they have a 45% heal nerf to Heroes).She would still be able to target them but only if the healers have the “toggle mode” disabled. I think it should look similar to the toggle of the Grand Warden, that’s my pitch, what do you guys think? I know there has been a similar post https://forum.supercell.com/showthread.php/17470-Ground-mode-for-level-4-healers-favorite-targetingBut I find this is a more refined idea, and locking those abilities to certain levels would not promote sportsmanship in my opinion. And example of what it could look like in battle!
